As we can see here the Xserver reports that it can only do one resolution, so any KDE tool can not offer anything else. > A related problem is, that the gamma value of the screen can't be set any > longer.

This again looks like some change unrelated to the KDE update is at fault but more likely something related to the Xserver (or display driver, etc).
